ANTIFRICTION-BEARING.

Specification of Letters Patent. Patrenfjedl Aug. 29, ll llfia Application filed January 4, 1913. Serial No. 740,116.

To all whom it may concern:

Be it known that 1, JOHN H. MODLER, a subject of the Emperor of Germany, and

' resident of Schweinfurt-on-the-Main, Germany, have invented certain new and useful Improvements in Antifriction-Bearings, of which the following is a specification.

The object of my invention is to provide a roller bearing having inner and outer members each provided with annular raceways between which are located a plurality of sets of rollers, the rollers of each set having their working surfaces in different but parallel planes between the corresponding raceways, and meansto retain said sets of rollers in operative position betweensaid members.

In a preferred embodiment of my invention, the working surfaces of the rollers are graduated in such a way that they are touched by converging lines that meet at one point in the line of the axis or in the center line of the bearing, the corresponding raceways of said members being correspondingly arranged in said line.

My invention further comprises novel del tails of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure l-is a partly sectional side elevation of a roller bearing embodying my intainer for the rollers; Fig. 4 is a sectional I detail of Fig. 4; Fig. 5 is a partly sectional side view of a modified-form of roller bearing, in' which the rollers are graduated in diameter and concentrically disposed, but the surfaces of the sets of rollers are not touched by the same lines that touch the same point in the center line of the bearing; Fig. 6 is a sectional detail of a modified form of bearing wherein the surfaces of the rollers and the corresponding raceways are in parallel lines, but the rollers are not concentrically disposed; Figs. 7 and 8 are sectional detail views of modified forms of Fig. 6 Fig. 9 is a sectional detail view illustrating the bearing provided with rollers having curved working surfaces and the raceways having plane surfaces; Fig. 10 is a similar view illustrating a bearing wherein the rollers have cylindrical surfaces and the opposed raceways have curved and plane surfaces respectively, and Fig. 11 is a similar view illustrating the rollers and raceways having curved surfaces.

Similar numerals of reference indicate corresponding parts in the several views.

In the form of the bearing shown in Figs. 1 and 4, the inner and outer members or rings 01 and e are respectively provided with opposed similarly disposed raceways for the interposed sets of rollers 2. The rollers are shown in sets in cylindrical form, and the raceways Z, m, n, of the inner member a? and the raceways h, i, .lc,.of the outer member e are parallel to the axes of the respective sets of rollers. The diameters of the rollers of each set of rollers vary from the rollers of the other sets, and the raceways are arranged in such a way that the converging lines f, 9, meeting at the point 6 in the line of the axis a of the bearing, touch the raceways, h, 2', k, and Z, m, n, respectively, at some point. In all the views of the drawings I have shown three sets of rollers, and corresponding raceways for such rollers, although it will be understood that any do sirednumber of sets of rollers may be provided, with a corresponding number of raceways. The rollers 2 are maintained in proper working relation by a suitable retainer or cage, which, in the examples illustrated, comprises suitably shaped rings 3, 4, connected together by separators 5, between which parts of the retainer the several sets of rollers are located to freely rotate. The separators 5 may be in the form of suitably shaped blocks, preferably having curved surfaces at 5 (Fig. 4*) corresponding to the opposed I0llers,. having their end portions passing through the rings 3, 4, and riveted firmly thereto, or such separators may be journaled in the rings 3', 4, if desired.

In Fig. 1 it will be seen that while the rollers are of graduated diameter and have cylindrical surfaces, they are symmetrically arranged between the opposed pairs of raceways k, n, i, m, and 72., Z, which are located concentrically with respect to one another, but correspondingly touched by the respective lines 7", g.

In Fig. 2 the outer member 6 has a single and are thus so graduated h each set lie-in in Fig. up by movmg the lnner center line a of the raceways Z, m, n,

plane raceway surfaces of the rollers of each set bear, and the inner member at has ways 2?, u, 1), such raceways cally disposed with respect to the axial lines of the rollers, while the raceways t, 'u, v, are respectively parallel to the racewa that theline a: which meets theaxial or center line 0 of the hearing at the point p, ways, and the line 8 which meets line 0 at being concentrithe point 9 lies in the raceway g, the line 3 touching the axes of the the point p of line 0.

In Fig. 3 the relative arrangement of parts shown in Fig. 2 is reversedathat is to say, the outer member 6 is provided with rollers and meeting graduated raceways e, f, g, and the inner member d is provided with the plane raceway I), the rollers 2 being correspondingly graduated to engage said raceways as shown, the raceways e, f, g,being each parallel to the raceway b. .In this form of bearing the raceways e, f, g, meets the axial or center line a of the bearing at the point a, and the line 03, which lies in the raceway b, meets line a at the same point a, the line is which touches the axes of the rollers also meeting the point a.

In the examples of the bearing illustrated in Figs. 1 and 3 wear of the bearing maybe taken up by moving the inner member 0! inwardly, while in the example illustrated with the rollers inwardly, with respect to the outer member. p

In thefexample illustrated in Fig. 5, the

relative arrangement ofv the parts is sub-- stantially the same as that shown in Fig. l, but the raceways k, z, is, do not all touch a line meeting at a' point 5 with the axis or do not touch a line meeting at said point with the line a. a

-In Fig. G'the rollers are ofthe same diam? eter and the surfaces .of all the rollers of parallel planes, theraceways 72., Z, i, 'm, and la, n, being correspondingly arranged, but the axes of the rollers of each set are not concentric, andlines parallel with the surfaces of the rollers are also parallel with the axes of the rollers, butnone of the roller surfaces or line. T I

In Fig. 7 the relative arrangement of the member's d, e, and the raceways are substanraceways are in the same so proportioned and graduated ofthe bearing at the point awhere the line a? from the raceway b, so thatthe raceways e, f,

9 against which the outer graduated race touches said race:

touch the line i that the raceways e, f, 9

surfaces,

and the raceways have convex surfaces. According to my improvements, --ing a plurality of series of rollers,' each series comprising apluralityof rollers, said bearing, and likewise the' to that shown in Fig. 3, ex-

that their axes do notmeet' the raceway b meets the line a, and the raceways e, f 9 are parallel and graduated in distances from corresponds substantlally in arrangement to Q that shown in Fig. 2, except that the axes of the rollers do not touch the axial line 0 of the hearing at the point p where the line 8, which touches the raceway g, meets the line 0, and the raceways t, u, 'v, are parallel and graduated in distances from the raceway g,

so thatthe raceways t, u, v, are not all touched by a line point 7).

While I have described the rollers as cylindrical-and the raceways as having c0rresponding plane surfaces, to coact with such rollers, it is not essential that the rollers and raceways have absolutely cylindrical surfaces, as the rollers or the raceways, or both, may have curved surfaces, such as outwardly curved or convex surfaces, as illustrated in meeting the line 0 at the Figs. 9, 10 and 11.

In Fig. 9 the rollers 2 are shown provided with outwardly curved or convex surfaces adapted to bear against raceways having cylindrical or plane surfaces, the arrangement of parts other than above in Fig. 9 corresponding substantially to Fig. 7, although the arrangement of the curved and plane surfaces of .the rollers and raceways may apply-to either'of the figures. 2 wear of the bearing maybe taken member cl together In Fig. 10 the rollers and raceways are arranged relatively the same as in Fig. 9, except that the rollers are cylindrical and ave curved convex and the raceway b is cone-like.

The relative arrangement of the shownin Fig. 11 is generally substantially the same as in Fig. 5, except that the rollers outwardly curved or by havrollers and racewaysbeing graduated in diameter, and havingtheir surfaces touching hnes that meet a common point with the axes of the respective series of rollers in a line passing through theaxis. of the bearing, or by having the surfaces of the rollers and raceways in parallel lines with the opposite parts sides of the'same the rollers not touching or coinciding with the same lines, either parallel with or at an angle to the axes of the rollers,

bearing against opposedconically .disposed surfaces, tending to act in a wedge-like manner dueuto end thrusts of the: members of the bearing, is obviated,-but,' by the arran ements set forth herein, the advantages 0 .a conical bearing havin anti-friction rollers is attained, with gratlu surfaces which do not,

ated rollers havin in conjunction wit the disadvantage of conical rolle I and outer members, and a plurality of sets inseam the corresponding raceways, act at any time in a wedge-like manner, whether the surface be cylindrical or convex. Furthermore, the

sliding tendency of conical rollers to get out row as desired, and each roller, located between correspondingly narrow raceways, the

surfaces of which correspond in parallelism with the surfaces of the rollers coacting therewith, do not tend to rotatively control other rollers of the same set, so that twisting or cramping of relatively long cone-like rollers between correspondingly disposed raceways, is overcome, by having the surfaces of each roller and its opposed raceways parallel.

An anti-friction bearing having inner and outer members, and a plurality of sets of rollers between said members having their surfaces inclining toward the axis of the bearing in graduated parallel lines, said members havln r raceways coacting with said rollers and inclining toward said axis, one line drawn from a common point in said axis passing through each one of the raceway surfaces correspondingly on opposite sides of said rollers.
